Description

Device for packing cigarettes or similar objects The invention relates to devices for packaging cigarettes or the like Objects in which the objects to be packaged from a storage container get through vertical guide channels on a guideway on which they fed to a collecting container in layers. One has this with devices Art already proposed, one for the automatic removal of incomplete layers Provide separating device by interacting with the cigarettes Feeler lever is controlled. Now, the main purpose of the present invention is to Eliminate the incomplete layers in a particularly simple and effective manner accomplish, by the fact that the movable feeler lever with a constantly interacting locking axis moved back and forth, through the displacement of which an inactivity occurs the Ausscheideaorrichtung, for example the rotation of one in the conveyor track of the Cigarettes arranged pivoting plate, which is prevented, however, at the lack of a cigarette by changing the position of the associated feeling love so that the separating device can come into operation. To go into activity the Ausscheidevorriclitung the lack of the relevant cigarette layer in the further Compensate for the operation of the device, according to the invention is preferably the Arrangement made so that when leaving the incomplete cigarette layer at the same time a coupling device is activated, through which the Drive .the other located behind the feed path of the cigarette layers Equipment for filling and packing cigarettes for the duration of a work cycle is interrupted.

The wall of the vertical guide channels that make up the cigarettes get on the guideway, are useful according to the invention in the transverse direction to the cigarettes constantly moved back and forth in order to arrange the cigarettes in layers to facilitate in the guideway. It has already been suggested that the walls to arrange the guide channels movably, however, it is found in the known devices, in which the movement of the walls takes place in a vertical direction, the disadvantage, that with the upward movement of the walls easy damage to the bar overlying Cigarettes can enter. This disadvantage occurs when moving back and forth the walls of the guide channels avoided transversely to the cigarettes. Preferably this movement takes place in such a way that the walls of the guide channels in the Are rotatably mounted near their lower ends and for example by at their Pivot axes attached and with a constantly moving back and forth rod or the like. related crank arms are caused to oscillate back and forth.

The one at the end of the guideway arranged Cigarette layers stacked on top of each other are collected in the preferred embodiment Embodiment of the device in a known manner by a plunger in inserted on a rotating turntable in increments, which according to the invention are besieged rotatably about horizontal axes and after arrival over a Föriderbahn or the like, together with a previously placed cigarette packet be rotated by iSo ° so that the cigarette packets with the cigarettes after Stripped from the bottom of the containers and brought onto the conveyor belt or the like can. It is expedient to strip off the filled cigarette packets by the drive .the device up and down moved stamps, which by on through slots or recesses provided in the bottom of the container.

In the drawings, i is a downwardly tapering funnel-like shape Cigarette container on: the bottom of which by vertical walls 2 a number of Guide channels is formed. The walls 2 are pivotably mounted on rails 3 Axles 2Q attached, at one end of which crank arms ¢ sit, the other at a horizontally displaceable rail 5 are hinged to the one end carries a roller 6 and by a spring 7 against a with a vertical Guide rod 9 connected curve piece 8 is held. The cam rod 9 is standing through handlebars 9 "with a crank disc 9b in connection, which is from the drive wheel 9, the device is set in rotation, so that de guide rod 9 constantly moving up and down. A guide track f o is provided below the walls 2, which has a number of grooves i o, which after the filling device to gradually narrow. In the upper part of the cigarette container i there are two Plates i i arranged. The advance movement of the cigarettes to be packaged on the Guide track io is made by driving rods i2, the lateral ends of which are attached to? Tutes 12 "are attached, which are guided over sprockets i2b and 12. The sprockets 12b are continuously set in rotation by the drive pulley 9 of the device. On the top of the cigarette container i two guide strips 13 are attached, into which a cigarette container, not shown in the drawing, is inserted can be determined which # after emptying through a previously filled, full container is replaced.

One of the number of grooves is located above the guide track io of the cigarettes ioa corresponding number of sensor rollers 14 are provided, which are loose on a shaft 16 seated Fühlheb.eln 15 are stored. A lever 17 is also located on the shaft 16 fixedly arranged, which carries a horizontal rod 18 at its free end, which can be brought to bear against the upper ends of the Fü.hlhebel 15. on .The shaft 16 is also a lever ig .befestigt which at its free end a carries lateral stop pin 2o, which is attached to the guide rod 9 with a Approach 21 interacts (Fig.7). Below the feeler lever 15 is a locking bar 22 arranged displaceably, which at its end facing the guide rod 9 a roller 23 carries which by a provided at the other end compression spring 2d. . Against a curved piece 25 attached to the guide rod 9 is pressed.

The guide path fo is interrupted behind the lower end of the cigarette container i by a swivel plate 27 which is mounted at 26 so that it can swivel downward. A shaft 28 is fixedly connected to the swivel plate 27 and carries an angle lever 29, the upper end of which cooperates with a stop 33 provided on the locking rod 22. At the end of the axle 28 facing the guide rod 9, a lever 3o is also attached, which at its free end carries a roller 31 which rests against a curved piece 32 attached to the guide rod 9. Against the lower end of the angle lever 29, under the pressure of a spring 43, lies a lever 42a mounted on a rotary shaft 43a, through which the roller 31 is also held against the cam piece 32 to rest. At the end of the axle 43u facing away from the lever 42, a downwardly extending lever 142Q is attached, which has a kidney-like attachment at its lower end. This hammer-like approach lies laterally next to (1-2r path of movement of a number of bolts 37 , which are arranged displaceably in the longitudinal direction on a rotating disc 36 Lifting pawl 39 engages. On the axis of the switching lever 4o sits a lever 4oQ which carries a roller and which is held by a spring 4o6 against a cam piece 41 fastened to the guide rod 9 on which a tension spring 44t acts. Parallel to the slide 44 is a countershaft 34 driven by the drive disk 9, on which a disk 34Q is attached which carries a pawl 35, which is usually connected to a disk 35 , provided for driving lug is engaged. at its other end, the pawl 35 has a neck on which at your circulation of the disc 34a circling past immediately in front of the front end of the slide 44. At the end of the guideway fo facing away from your cigarette container there is a Samniel container for cigarettes fed in layers, which consists of a bottom 45 movable in a vertical direction, two side walls 46 and a transverse wall 4, 7 designed as a pusher (Figs. 12 to 14 ). The plunger 47 is arranged displaceably in the horizontal direction in a guide 73 and is connected to a lever 74 which is connected to a double lever 55 which is pivotable about an axis 75 and which carries a roller 76 at its free end, which against a cam disk 54 applied, which is attached to an axis 34U connected to the drive plate 35.

Above the collecting container 46 there is arranged a pressure plate 57 which is fastened to a lever 58 and which can be moved up and down by means of a cam disk (not shown) which is seated on the axis 34U. A cam disk 48 is also seated on the axis 34b, against the circumference of which a roller 77 mounted on a lever 49 pivotable about the axis 75 rests. The free end of the lever 49 is connected by a link 78 to a lever 8o fastened on an axle 79. A lifting pawl 5o is arranged on the lever 8o and engages in a ratchet wheel 51 which is loosely seated on the axle 79 and which is connected to a cam disk 52 with multiple steps. A roller 83 mounted on a lever 82 pivotable about an axis 81 rests against the circumference of the cam disk 52. A lever 53 is also attached to the Aelise 8i, which is articulated to a rod 84 which carries the base plate 45 of the container and which is mounted in a bearing stand 85 so as to be displaceable in the vertical direction.

Behind the collecting container 46, a turntable 6o is arranged to be rotatable about a vertical axis 86, on the circumference of which a number, in the present case six, cigarette containers 56 are rotatably mounted in carriers 59. The turntable 6o is rotated intermittently by means of two levers 62, 63 fastened on the axis 6o provided lugs 87 cooperate. On the shaft 67 of the drum cam 61 there is also a cam disc 68 which controls a locking pin 66 which, after each switching of the turntable 6o, comes into engagement with the locking jaws provided on this. On the side of the turntable 6o facing away from the laminate storage tank, a conveyor belt 72 is arranged on which the cigarettes are placed in the boxes 88 placed on the containers 56. The required rotation of the container 56 with the boxes 88 placed on it is brought about by a Zalinseä, -ment 69 moved by an eccentric (not shown) by means of a rod 89, which is connected to a cigarette container 56 moved on the pivot axis of the conveyor belt 72 attached gear 70 comes into engagement. For ejecting the boxes 88 filled with cigarettes after the containers 56 have been turned over, a punch 71 is provided which is attached to a carrier gi which is movable in the vertical direction and controlled by a rod 9o from an eccentric (not shown). During the working movement of the carrier gi, the punch 71, which in the present case consists of four vertical pins, passes through slots 92 provided on the bottom of the container 56 and thereby pushes the filled cigarette box 88 down until it is on the conveyor belt; 2 rests.

The operation of the device is as follows. The cigarettes to be packaged are filled into the cigarette container i by hand or by means of an attached storage container and slide along its walls and the inclined plates ii into the lower part of the container. Here the cigarettes arrive in guide channels formed by the walls 2, whereby the placement of the cigarettes in the channels is supported by the fact that the walls 2, through the intermediary of the rod 5 and the crank arms 4, have a constant reciprocating movement of the Curved piece 8 bearing guide rod 9 is granted. At the lower end of the guide channels, the number of which corresponds to the number of cigarettes that are supposed to form a layer in the pack, the cigarettes get into the grooves ioa of the guide track io. Such a large space is provided between the lower ends of the walls 2 and the guide track io that the driver rods 12, which are constantly being moved forward by the chains i2a, can move between them, so that the cigarette layers are advanced on the guide track io, whereby they simultaneously as a result The gradual narrowing of the grooves 1 0 "are also pushed together laterally so that they finally lie completely, lightly against one another. At the beginning of their advance, the cigarettes get under .the rollers 14 of the feeler lever 15, which consequently in the position shown in Fig.9 in which they are out of engagement with the locking rod 33. The locking rod 22 can consequently shift laterally under the action of the spring 24 when the roller 23 runs off the cam piece 25 provided on the now downwardly moved guide rod 9, and at the end During this movement, the stop 33 provided on the locking rod 22 comes into engagement with the angle lever 29 and keeps this in the in A'bb. 7 position shown. This prevents the roller 31, of the lever 30 fastened on the axis 28 of the pivot plate 27, from sliding up the curve piece 32 during the further downward movement of the guide rod 9 and the lever 3o from swinging out. As a result, when the cigarette layer advanced by the driver rods 12 is complete, the swivel plate 27 remains in the position shown in Fig. 7, in which it forms an extension of the guideway so that the cigarettes over the plate to the collecting container 46 can be advanced.

However, as soon as the cigarette layer passing through the guide channels from the cigarette container i into the grooves ioa of the conveyor track io is not complete, i.e. one or more cigarettes are missing, the feeler lever 15 located above the unfilled guide grooves can after the release of the one connected to the rod i8 Lever i9 through the stop 2i of the downward moving guide rod 9 move so far down until the sensor roller 14 rests on the .Förderbahn io. Here, the sensing levers 15 enter recesses provided on the locking rod 22 and thereby prevent the locking rod from moving sideways. The consequence of this is that the stop 33 of the locking rod 22 does not come into engagement with the upper end of the angle lever 29 and the roller 31 of the lever 30 can move freely under the action of the spring 43 on the cam 32 of the downwardly moving guide rod. The axis 28 is rotated and the swivel plate 27 attached to it is deflected downward, so that the entire incomplete position on the swivel plate 27 slides downward and is eliminated from the operation. Simultaneously with the pivoting of the plate 27, the double-armed lever 42 also rotates about the axis 43 "so that the hammer-like approach provided at its lower end comes to rest against the bolt 37 just next to it and pushes it forward so far that it over the other Side of the disk 36. During the further intermittent rotation of the disk 36, the protruding end of the relevant bolt 37 comes to rest against the front end of the slide 44, so that it is advanced against the action of the spring 4d.b. Movement of the pawl 35 seated on the constantly wmfaufenden disk 2.1a on the slide 44 then hits the rear approach of the pawl 35 on the protruding part of the slide 44, so that the pawl 35 is rotated and disengaged from the 1V internal nose of the disk 35a ' The shaft 34b (A.bb. 12), which is firmly connected to the disk 35a, is consequently stopped during one revolution of the disk 34, so that the drive of the moving parts of the collecting container 46 as well as the switching of the turntable 6o and the devices interacting therewith are interrupted for the duration of a work cycle. This interruption compensates for the missing cigarette layer in the operation. After the advanced bolt 37 has passed the slide 44, the latter moves back into its rest position under the action of the spring d..lb. With the further rotation of the disk 36, the bolt 37 is then also pushed back into the usual position by a curve which is attached next to the disk and is not shown in the drawing.

The complete layers of cigarettes are pushed forward by the driving rods i2 in uninterrupted movement up to the end of the guide track io and introduced into the collecting container .16 (Fig. 12), the bottom 45 of which, after each cigarette layer has been fed through the cam plate 48 by means of of the ratchet gear 5o, 51 stepped disk 52 switched stepwise is lowered by the height of a cigarette layer. At the same time, the lever 58 is moved by the cam disk (not shown) in such a way that the plate 57 is pressed from above against the "cigarette layer" and thereby prevents sticking to the carrier rods 12 or any other undesired displacement of the cigarettes (Fig. 13) The desired number of layers of cigarettes has been filled into the collecting container 46, the transverse wall 17, designed as a pusher, is advanced by the cam 5.1 so that all the cigarettes are pushed into the cigarette container 56 of the turntable 6o located behind it (Fig. 1.1), whereupon the pusher moves. 17. When the turntable 6o is switched again by the ratchet mechanism 63, 6.1 moved from the drum cam 61, a cigarette box 8o is then slipped by hand over the container 56 that is open at the front and top with the box 88 on top of the conveyor belt 72, where there s gear 70 attached to one end of its pivot axis comes into engagement with the Zabnseginent 69 so that the container 56 is rotated by 180 ° during the subsequent movement of the toothed segment 69. The bottom of the box 88 is now turned down. After the container 56 has been rotated, the carrier 9i moves downwards, so that the punch 7r passes through the slots 92 in the bottom of the container 56 and presses the filled, open-topped box downwards onto the conveyor belt 72. The boxes 88 filled with cigarettes are then fed by the conveyor belt 72 to a point at which the pack is completed by putting on a lid, which can be done in any desired manner.

The invention is, of course, structurally not limited to the one shown Embodiment limited, rather various modifications can be made to this can be made without exceeding the scope of protection.
